* blockchain: kill ioservice on scope end, rather than manuallymoneromooo-monero2015-12-301-6/+7
| | | | | | This ensures this will be done without fail, as the error prone matching of every return with a call to KILL_IOSERVICE leads to hard to debug corruption when one is missing.

* | blockchain: Fix height in call to on_blockchain_decmoneromooo-monero2015-12-261-1/+1
|/ | | | It was a noop anyway
* blockchain: fix a few block addition bugsmoneromooo-monero2015-12-251-34/+45
| | | | | | | | | | | | | | | | | | | | | If the block reward was too high, the verification failed flag was set, but the function continued. The code which was supposed to trap this flag and return failure failed to trap it, and, while the block was not added to the chain, the function would return success. The reason for avoiding returning when the block reward problem was detected was to be able to return any transactions to the pool if needed. This is now mooted by moving the transaction return code to a separate function, which is now called at all appropriate points, making the logic much simpler, and hopefully correct now. We also move the hard fork version check after the prev_id check, as block which does not go on the top of the chain might not have the expected version there, without being invalid just for this reason. Last, we trap the case where a block fails to be added due to using already spent key images, to set the verification failed flag.

* blockchain: reinstate double spending checks in check_tx_inputsmoneromooo-monero2015-12-251-3/+7
| | | | | | This fixes some double spending tests. This may or may not be unneeded in normal (non test) circumstances, to be determined later. Keeping these for now may be slower, but safer.
* blockchain: make some flag twiddling code closer to the originalmoneromooo-monero2015-12-251-2/+2
| | | | Probably paranoid and unnecessary
* blockchain: fix bitflipping test with quantized block rewardsmoneromooo-monero2015-12-251-1/+4
| | | | | | | Block reward may now be less than the full amount allowed. This was breaking the bitflipping test. We now keep track of whether a block which was accepted by the core has a lower than allowed block reward, and allow this in the test.
* blockchain: add missing m_tx_pool.on_blockchain_decmoneromooo-monero2015-12-251-0/+1
| | | | | It was missing in the port to DB. This is actually a noop, so should not have functional changes.
* blockchain: fix switch to alternative blockchain for more than one blockmoneromooo-monero2015-12-251-1/+1
| | | | | When rolling over more than one block, the db height will decrease, but the split height should be constant, as per the original code.
* blockchain: add a missing validity check to rollback_blockchain_switchingmoneromooo-monero2015-12-251-0/+6
| | | | It was present in the original code
* core: catch exceptions from get_output_keymoneromooo-monero2015-12-251-2/+18
| | | | | This can happen when trying to find an amount that does not exist, and fixes a core test.
* db: throw when given a non txout_to_key output to addmoneromooo-monero2015-12-251-0/+5
| | | | | | The check was explicit in the original version, so it seems safer to make it explicit here, especially as it is now done implicitely in a different place, away from the original check.
* Allow the wallet to access hard fork informationmoneromooo-monero2015-12-191-2/+2

|
* add a --fakechain argument for testsmoneromooo-monero2015-12-131-4/+7
| | | | | | | | | | | The core tests use the blockchain, and reset it to be able to add test data to it. This does not play nice with the databases, since those will save that data without an explicit save call. We add a fakechain flag that the tests will set, which tells the core and blockchain code to use a separate database, as well as skip a few things like checkpoints and fixup, which only make sense for real data.
* blockchain: log block (not chain) height in "BLOCK SUCCESFULLY ADDED"moneromooo-monero2015-12-131-1/+1
| | | | | This makes it log the same height as the original code, which is less confusing when comparing behaviors.
* blockchain: fix off by one in get_blocksmoneromooo-monero2015-12-131-1/+1
|
* blockchain_db: fixup missing key images in early DB versionmoneromooo-monero2015-12-061-0/+3
| | | | | | | | | | | Early DB versions did not store key images for inputs if the transaction spending them had no outputs (ie, all fee). This is not correct, as this would allow these outputs to be double spent. This was fixed in 533acc30eda7792c802ea8b6417917fa99b8bc2b a few months ago, but databases having synced blocks 2021612 and 685498 with a faulty version will be missing those key images in the spent keys database. This code checks for this, and adds those key images if they are missing.
* hardfork: fix more major/minor issuesmoneromooo-monero2015-11-241-2/+2
| | | | | | | | | | | Also add some more tests, and rename some instances of "version" and "add" for clarity. NOTE: the starting height values are sometimes wrong. I suspect this is due to the hard fork reorg code being buggy, since they're good when syncing after the fact. However, they're not actually used by the consensus code, so I'm ignoring this for now, but this needs debugging.

* Relay transactions when they linger too long in the poolmoneromooo-monero2015-11-211-4/+16
| | | | | | | | The last relayed time of a transaction is maintained, and transactions will be relayed again if they are still in the pool after a certain amount of time, which increases with the transaction's age. All such transactions are resent, whether or not they originated on the local node.

| * Fix leak on real output when using a very recent outputmoneromooo-monero2015-10-251-0/+11
| | | | | | | | | | | | | | | | The wallet and the daemon applied different height considerations when selecting outputs to use. This can leak information on which input in a ring signature is the real one. Found and originally fixed by smooth on Aeon.

* / hardfork: switch voting to block minor versionmoneromooo-monero2015-10-211-2/+2
|/ | | | | | | | | | | | Using major version would cause older daemons to reject those blocks as they fail to deserialize blocks with a major version which is not 1. There is no such restriction on the minor version, so switching allows older daemons to coexist with newer ones till the actual fork date, when most will hopefully have updated already. Also, for the same reason, we consider a vote for 0 to be a vote for 1, since older daemons set minor version to 0.
